> Would be nice to have a suggester that can handle some fuzziness (like spell
> correction) so that it's able to suggest completions that are "near" what you
> typed.
> As a first go at this, I implemented 1T (ie up to 1 edit, including a
> transposition), except the first letter must be correct.
> But there is a penalty, ie, the "corrected" suggestion needs to have a much
> higher freq than the "exact match" suggestion before it can compete.
> Still tons of nocommits, and somehow we should merge this / make it work with
> analyzing suggester too (LUCENE-3842).
